LOCK-CUTTING MACHINE FOR BARREL-HOOPS.

Specification of Letters Patent.

Patented Nov. 17', 1908.

Application filed May 29, 1902. Serial No. 109,455.

To all whom it 'may concern:

Be it known that we, EDWARD HOLMES, BRITAIN HOLMES, and EDWIN F. BEUGLER, citizens of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Lock-Cutting Ma.- chines for Barrel-Hoops, of which the following is a specification.

This invention relates to a machine for cutting locks on barrel hoops and the like which is automatically driven by power, the operator being merely required to feed the hoop blank into the machine where it is gripped and held while the cutters automatically cut the locks therein.

The main objects of the invention are to cut the locks automatically by machine power without the assistance of an operator.

One feature of the invention relates to the adjustability of the cutting devices so that the locks may be cut at different points.

The invention also relates to certain details of construction all of which will be fully and clearly hereinafter described and claimed reference being had to the accompanying drawings, in which,-

Figure l is a side elevation of the improved machine. Fig. 2 is a vertical longitudinal section on line a c, Fig. 3. Fig. 3 is a top plan view of the machine. Fig. 1 is an end elevation. Fig. 5 is a vertical transverse section on line Z) b, Fig. 3, looking in the direction of the arrow V. Fig. 6 is an enlarged detached side View of one of the lock cutting mechanisms and its frame. Fig. 7 is an enlarged detached end view of one of the cutter frames with the lock cutting mechanism mounted therein. Fig. 8 is an enlarged detached side view of the double cutter. Fig. 9 is an enlarged detached end view of the double cutter looking in the direction of the arrow IV, Fig. 8. Fig. 10 is a top plan view of the cutter frame with the cutting mechanism removed. Fig. 11 is an enlarged detached side view of one of the supports for the hooks. Fig. 12 is a detached side view of one of the lever stops also showing a section through the supporting bar. Fig. 13 is an enlarged detached end view of one of the lever stops with afragment of its supporting bar. Fig. 14 is an enlarged detached view of one of the cutter operating loops and its hook. Fig. 15 is an enlarged detached plan view of the hook supports shown in Fig. 11.

Fig. 16 is an enlarged detached plan view of one of the weight supporting bars.

In referring to the drawings in detail, like numerals designate like parts.

The frame of the machine is preferably of a rectangular form having a top bed 1, and vertical end parts 2. A horizontal longitudinally extending shaft 3, is journaled in t-he frame and is provided with a gear wheel 4, which meshes with a gear wheel 5, on a short driving shaft 6, on which power transmitting pulleys 7, are mounted. A cross head 01 block 8, is mounted in slideways 9, in each of the end frame parts 2, so as to slide vertically therein and these two cross heads or blocks are connected by a horizontal bar 10. A crank 11, is mounted at each end of the shaft 3, and has a crank pin 12, and connecting rods 18, each mounted at its respective ends on the pin 12, and a pin 14, projecting laterally from one of the heads or blocks 8, serve to operatively connect the heads or blocks to the shaft 8, so that the rotation of the shaft 3, will impart a vertical reciprocating movement to the blocks S.

The lock cutting mechanism is operated from the horizontal connecting bar 10.

A cutter frame is mounted on the bed 1, near each end thereof, and one of these frames designated by the numeral 15, is fastened rigidly to the main machine frame and another designated by the numeral 16, is adjustable longitudinally so as to provide for hoops of different lengths and for cutting locks at different distances apart. y

A rock shaft 17, is supported in each frame between the opposed cone points 18, of screw bolts 19, see Fig. 7, and is slightly at an angle to the horizontal; one end of the rock shaft being in a slightly higher plane than the opposite eXtreme substantially as shown in Fig. 7, to give the desired angle to the cutter blades 20, mounted on said rock shaft.

As the lock at one end of the hoop is cut on the side opposite to which it is cut at the other end, the cutters are arranged to out oppositely to each other, z'. c. one cutter cuts downward to the right and the other cuts downward to the left.

It will be noted that two critters are mounted on the rock shaft shown in Figs. 7, S, and 9. The object of this is to cut two locks at one end of the hoop, the outer one of which weakens the wood so that the operator can twist off the projecting end (which is provided as a convenient grasping portion for the operator) after locking the two extremes of the hoop together.

The shaft 17, is rocked by a loop device which loosely encircles the bar 10, and has connection to a lateral extension or crank projecting from the rock shaft. The preferred construction of the loop device is shown in Fig. 14, in which a substantially U shaped portion 21, has its upper ends passed through and secured to a plate 22, by opposed lock nuts 23. A hook 24, has its lower extreme passed through and secured to the plate by lock nuts 25, and is adapted to hook in an opening 26, formed in a lateral extension.

The cutters 20, and their supports are formed preferably as shown in Figs. 8 and 9.

A hub 27, is mounted on the rock shaft and is fastened against independent rotation by a set screw 28. Two lugs 29, and 30, project from the hub at substantially right angles to each other, see Fig. 8. A support 31, for the cutter blades 20, is secured to the substantially vertical lug 29, by a bolt 32, and is longitudinally adjustable to vary the position of the cutter blades.

The support is substantially of the same hook form as the cutter and is provided with a shallow longitudinal groove indicated by dotted lines in Fig. 9, in which a central longitudinal rib 33, projecting from the lug 29, lits and slides to prevent lateral or twisting movement of the support.

The cutter blade 20, is adjustably fastened to the support 31, by a bolt 34, which passes through a slot 35, in the vertical portion of the blade, as shown in Fig. 8. Usually however all of the adjustment necessary is obtained by moving the support- 31, and the cutter block is locked to the support with its inner surface in close contact with the support to strengthen the same as shown in Figs. 7 and 9.

An extension block 36, is secured to the approximately horizontal lug 30, by a screw bolt 37, and is provided with the opening 26,

as before described, near its outer extreme shown in Fig. 8, in which the hook 24, engages. The extension block 36, is longitudinally adjustable relatively to the lug 30, and has a shallow longitudinal groove 39, in which a longitudinal rib 40, projecting from the side of the lug 30, engages and slides as shown in Fig. 9. An eye 41, projects from the hub to which the upper end of a spring 42, is secured. This spring automatically returns the cutter to its initial position after the cutting is performed. The hoop when the lock is cut is placed in flat position on the bed and is held in place by a plurality of hooks 43." The stems 44, of the hooks fit and slide in vertical slideways 45, in supporting blocks 46, mounted on the bed and formed substantially as shown in Figs. 11 and V15. rIwo of these slideways are also formed in the single cutter frame and three in the double cutter frame, see Fig. 3.

A horizontal bar 47, formed substantially as shown in Fig. 16, is placed on the lower end of each stem and serves as a support for weights 63, which pull the hooks down to grip the hoop by gravity. The bars 47, are secured to the stems by set screws 64. The hooks are raised'automatically by the elevation of the bar 10, which is vertically beneath the lower ends of the stems.4

Plates 48 and 49, are mounted on the cutter frames, see Fig. 3, and are each provided with curved depressions 50, for the passage of the cutters, the plate 48, having one depression and the plate 49, having two depressions to correspond to the number of cutters employed. The plates 48 and 49, are also provided with openings for the passage of the stems of the holding hooks, see Fig. 2.

The double cutter frame is adjusted horizontally on the main machine frame to vary the distance between the two cutter frames by a lever 51, which is pivoted to the rear of the machine frame and projects forward.

The lever is provided with a handle 52, at its forward end and a rod 53, is connected to an intermediate point on the lever and to the double cutter frame so that a movement of the lever will adjust the cutter frame longitudinally.

A horizontal bar 54, is secured to the front of the frame and has a series of stops 55, which serve to retain the lever in any position to which it may be adjusted, see Fig. 3.

The lever 51, has two downwardly extending pins 56, which are separated suiciently to fit on opposite sides of a center upwardly extending rib 57, formed on each stop 55,

substantially as shown in Figs. 12 andv 13, and thus hold the lever in its position. Vhen it is desired to release the lever it is liiloted sufliciently to disengage pins from the r1 The hoops are automatically kicked off of the machine bed after the locks are cutby a series of arms 58, which extendupward from a rock shaft 59, journaled in the machine frame at one side of the shaft 3. rlhe shaft 59, is rocked by a lateral lug 60, extending from the shaft 3, which strikes against a lug 61, extending from the shaft 59, after the cutters have operated and rocks the shaft 59, sufficiently to move the Lipper extreme of the arms 58, transversely across the machine and thereby throw the hoop offv the bed. The arms 58, are automatically restored to their former position after a hoop is thrown off by a spring 62.

The operation of the machine is as follows,-A hoop being placed in flat form on Athe bed, the holding hooks are drawn down and at the same time the cutters are operated by the depressing of the cross heads and cut the locks in the hoop. The cutters having operated the holding hooks move upward and release the hoop and the removing arms move transversely across the bed and force the hoop off of the frame. Another hoop is now placed in position and the operation is repeated.

This improved machine is entirely automatic in its operation, the hoop blank being gripped automatically by power means, the locks cut automatically by the cutters. and then automatically ejected from the machine. All that the operator has to do is to feed the hoop blanks into the machine.

The principal advantages of this machine reside in its simple construction, its automatic action and the cutting of all locks on each hoop simultaneously.
